Acer V5-471G Can't Read BIOS

[acata]

I have Acer V5-471G Can't Read BIOS.
BIOS IC is new and the old one also in good condition.
I already tried several BIOS DUMP, but Is still can't enter BIOS.
Once the laptop turns on, it just goes directly to os.

PIN 1 3.3V
PIN 2 3.0V
PIN 3 3.4V
PIN 4-6 0V
PIN 7 3.4V
PIN 8 3.4V

19.5v in 0.6a
5v ok
3.3 v ok
1.2v ok

Select Restart in Windows while holding the Shift key (or go to Settings/Updates and Security/Recovery/Advanced Start-up). From the Select UEFI settings in Advanced Troubleshooting.

remove hdd or ssd from your laptop, remove cmos battery also. When first booting, you should press F2 quickly. when you can enter bios, you need disable fast boot if your bios have this option
Hope this work

This one works so far.
But I still can't turn off the fast boot.
I have already tried another version of Acer v5-471 BIOS but I have had no luck

Some models of Acer need you to define an administrator password before allowing changes to these options. Try that.
